Abstract: PURPOSE:To perform switching from a telephone circuit part to a state where an automatic answering telephone circuit part can be used by remote control even when a user is not near by controlling a change-over switch to perform the switching of the telephone circuit part with the automatic answering telephone circuit by detecting the number of times of ringing of a call tone from the telephone circuit part. CONSTITUTION:The emission of the call tone is detected, and a call tone detection circuit 23 counts the number of times of ringing of the call tone, and when the call tone is rung for the number of times of ringing set in advance, a detecting signal (a) is transmitted to a switch control circuit 24, and the connection of the change-over switch 21 is switched, which validates the automatic answering telephone circuit part 25. When ringing is stopped in the state where the number of times of ringing is less than that set in advance, counting is initialized, and preparation for new ringing is set. Next, when an incoming call is received in the state where the movable contact of the changeover switch 21 is connected to B and the automatic answering telephone circuit part 25 is validated, the automatic answering telephone circuit part 25 is started up, and starts an operation as an automatic answering telephone set. In such a manner, it is possible to switch the telephone circuit part and the automatic answering telephone circuit part mutually even when the user is separated from the automatic telephone set.

Title: Control method for induction motor
Inventor: ISHII SHINICHI
IPC: H02P27/06
Filed: 1988-09-02
Abstract: PURPOSE:To similarly eliminate possibility of step-out and an overcurrent by judging an electric motor to be excessively, loaded, when its slip frequency is not less than a predetermined value, and decreasing an AC frequency, output by a PWM inverter, by the value of this slip frequency. CONSTITUTION:A current transformer 13 detects an electric motor current for calculation of a slip frequency at this moment. The obtained slip frequency fs is input to a speed adjuster 30: when a value of the slip frequency fs is within a predetermined value, the speed adjustor 30 changes a frequency command value f* at a predetermined change speed in a manner wherein the output frequency command value f* agrees with an input frequency preset value **. However, when the slip frequency fs is in not less than the predetermined value, this speed adjuster 30 outputs the frequency command value f* of value decreased by the value of the slip frequency fs, so that an induction motor 12 applies an AC frequency decreased lower by the value of the slip frequency than the value in the past, eliminating an overcurrent. Even a step-out can be eliminated because even the slip frequency is decreased.

Title: Integrating circuit
Inventor: TSUCHIYA SATOSHI
IPC: H03F3/34
Filed: 1984-10-19
Abstract: PURPOSE:To remove an influence of an off-set electric current of an operation amplifier by inverting and supplying an input signal to an operation amplifier for a prescribed period and removing the difference of the holding output before and after inversion in the integrating circuit handling a fine electric current input. CONSTITUTION:Switch circuits 5A and 6A go to on during the period T1, and a voltage E0 obtained at an output terminal of the operation amplifier 1 rises linearly. On the other hand, switch circuits 5B and 6B go to on during the period T2 and a voltage E0 falls linearly. A switch circuit 3 goes to on while a signal SW1 goes to a H level, a charging voltage of a capacitor 2 is instantaneously discharged and the voltage E0 is reset to zero. In sample holding circuits 7 and 8, a peak value of an ascending inclination and a peak value of a descending inclination of the voltage E0 are held. Consequently, a difference voltage of an output voltage of the circuits 7 and 8 can be obtained from a comparing circuit and this is double in a voltage value and becomes the voltage in which an off-set electric current of the amplifier 1 is removed.

Title: Production of wear-resistant article having tungsten carbide layer
Inventor: SUMIYA KATSUYOSHI
IPC: C23C28/04
Filed: 1988-09-02
Abstract: PURPOSE:To produce the title wear-resistant article having a high-hardness WC layer by nitriding a mild steel, heat-treating the steel at a high temp. in an inert gas, then forming a nickel phosphide-contg. layer by electroless plating, and further chemically vapor-depositing WC on the steel. CONSTITUTION:A mild steel is held at 500-530 deg.C for 30-50hr in a furnace supplied with gaseous NH3. Consequently, the steel is nitrided, and an iron nitride layer is formed on the surface. The steel is then held at a temp. higher than the nitriding temp., e.g., preferably about 30-50 deg.C higher while supplying an inert gas such as Ar into the furnace, for about 3-5hr to diffuse the iron nitride formed on the steel surface into the steel and to reduce the iron nitride layer. A layer contg. nickel phosphide is then formed on the iron nitride layer by electroless nickel plating. A WC layer is formed thereon by chemical vapor deposition. By this process, the adhesive strength of the WC layer to the steel is increased, and the title article having sufficient hardness and wear resistance is obtained.
